Our boat cost £15K 5 years ago and we've probably spent about 3K - prop shaft, prop, engine realignment, new loo, mattress, flooring etc, plus an external repaint which we could have done ourselves but couldnt give the time needed. Its a 1990 boat. The 2 way 12v /240v fridge, hob and cooker aren't the prettiest and newest but they work well and are clean. Having priced up new ones- I can't justify the cost when the current ones work well even if they arent particularly pleasing to the eye. There are plenty of ongoing costs with a boat, its down to priorities really. Next priority is solar which will give us a benefit when cruising. A new cooker and fridge wouldnt really give us a benefit for the cost involved.
